Details: Boston Duck Boat guided sightseeing tour (seasonal)
One of America's first cities, Boston straddles the Old and New World, its winding streets and busy harbor evoking Victorian England even while its skyscrapers and cutting-edge institutions reflect the American penchant for growth and change. See the city's (and nation's) origins at the Boston Common and State House, site of the Boston Massacre that helped spark the American Revolution. Copley Square and Back Bay bring to mind the literary Boston of Emerson, James, and Thoreau, with graceful houses and wide sidewalks testifying to the area's historic wealth (the posh area had more humble beginnings, however; it started out as a swamp!). The intellectual fervor continues in Cambridge, home to MIT, Harvard University, and all the students, cafés, and bookstores you'd expect in such a big-name college town. You'll also see Boston's North End, which the city's large Italian population has claimed for its own since the 1920’s. While the gelato and cannoli here may be sweet, they're no match for Boston's weirdest disaster -- in 1919, a giant storage tank of molasses collapsed, sending a 15-foot-high wave of the sticky sweet goo through the neighborhood and killing 21 people.
